It is much smaller than the other kids backpacks and therefore quite suitable even for children cribs.
The large bag must be opened with a simple click closure and secured with drawstring. All already for Small very easy to open. In front there is a small zippered compartment and the left and right small mesh pockets.
The straps are easy to adjust. In addition, there is both a breast and a waist strap with snap lock (for Small to open slightly heavier), which prevent a sliding back and forth of the backpack.
If I had to now look for something to complain, it would be the side pockets, which are in need of improvement. You could be a little deeper. Just as they are, they are wonderful for a thin hat or a box of tissues. A water bottle is already borderline, fall out fast times and also leiert the mesh from something.
